OF BOSTON, MASSACHUSETTS, A CORPORATION SPECIFICATION forming part ofLetters Patent No. 733,078, dated uly 7, 190

Application filed October 15,1902. Serial No. 127,364. (No modell) Toullwhom it may concern:

Be it known that I, GEORGE II. PIEEoE, a citizen of {the United States,residing at Quincy, in the county of Norfolk and State of Massachusetts,have invented new and useful Improvements in Ink-Distributing Mechanismfor Printing-Presses, (Case 0,) of which the following is aspecification.

This invention relates. to printing-presses,

and particularly to that class of printing presses in which theprintingis done upon a for Letters Patent ofthe United States, SerialNo. 88,500, filed January 6,1902, and allowed April 26,1902, and SerialNo. 112,448, filed June 20, 1902, and allowed August 18, 1902.

The improvement in the mechanisnr'lierefi inafter described as comparedwith the iin-' provements set forth in the applications hereinbeforereferred to consists, mainly, in add ing to the mechanisms shown anddescribed. in said applications a brayer-roll and mechanism to transferthe ink from an ink-supply roll, preferably journaled in anink-fountain, to a rotary ink-distribution plate; and, further, theimprovement consists in mechanism for moving the brayer-roll into andout of contact with the ink-supply roll and with said ink-distributionplate alternately, and, further, in mechanism for supplying anoscillatory movement to the brayer-roll while said distribution of theink more perfect than in the forms shown and described in theapplications hereinbefore referred to.

The invention consists in a form-carrier, a pivot therefor, mechanism torock said formcarrier upon its pivot, a rotatory ink-distribution platejournaled upon said form-cab 5o rier, an ink-supply roll, a brayer-roll,and

brayer-roll is in contact with said distribn mechanism to move saidbrayerroll alternately into and out of contact with said inkdistributionplate and with said ink-supply roll. 1

The invention again consists in the combination and arrangement of partsset forth in the following specification and particularly pointed out inthe claims thereof.

Referring to the drawings, Figure 1 isa pla view of my improvedink-distributing mechfanisin. Fig.2 is a' left-hand. side elevation ofthe same. Fig. 3 isa right-hand side elevation of the same. Fig. 3 is asectional detail taken on line 3 3*, Fig. 3. Fig. at isa 1 verticallongitudinal section taken on line a 4 of Fig." 1. Fig. 5 is a verticaltransverse sec- .tion, partly in elevation, taken on line 5 5 of .Fig.2. Figs. 6, 7, 8, 9, 10, 11, and 12 are diagram views illustrating thedifferent positions assunied during one rotation of the main shaft "of"the machine by the form-carrier, the ink-distribution plate, theink-carrier rolls, the brayer-roll, the rocker-arm upon whichsaidbrayer-roll is spring-supported,the rotary crank and the linkconnecting said crank and,

rocker-arm, and the pawl-and-ratchet mechanism by which the ink supplyor fountain roll is rotated. and Fig. 14 a front elevation, of amodified means of spring-supporting the brayer-roll upon the rocker-arm.

Like numerals refer to like parts throughout the several views of thedrawings."

In the drawings, 20 is the bed-frame of a The form-carrier 25 consistsof twoside arms 28 29, joined together by abase-plate 30. Said side arms28 and 29 are pivoted upon a rotary shaft 31, journaled in bearings 32and 33 upon the bed-frame 20. Said shaft 31 is Fig. 13 is a sideelevation,

guarded against longitudinal movement in its bearings by a collar 34,fast to one end thereof, and at the other end by the sprocketgear 35 andspur gear 36, keyed thereto. The

5 sprocket-gear 35 is rotated together with the spur-gear 36 by asprocket-chain 37, driven by another sprocket-gear fast to the maindriving-shaft of the machine. (Not shown in the drawings.) .At each sideof the form-carrier is a connecting-rod 38, pivotally connected to thearms 28 and 29 by a stud 39. The lower end of said connecting-rod may beraised and lowered by a crank-pin or any other appropriate mechanism,thus raising and lowering the form carrier 25 and rocking the same uponits pivotal shaft 31.

The paper 40 is fed intermittently by any suitable mechanism across theface of the pad 22 and below the base-plate of the formcarrier 25 andthe type 23, secured to said form-carrier, as hereinbefore set forth.

The ink is contained in a fountain 41, supported upon brackets 42 43,fast to the frame of the machine. An ink-fountain supply-roll 44 is fastto a shaft 45, j ournaled in said brackets 42 and 43. Rotary motion isimparted to the ink-supply roll 44 by a ratchet 46, fast to the shaft45, a pawl 47 engaging said ratchet and pivotally supported upon apawl-lever 48, to which pawl-lever a rocking motion is imparted by alink 49, pivotally connected at one end to said pawl-lever and at theother end thereof to the side arm 29 of the form-carrier 25.

A horizontal ink-distribution plate 50 is fast to a vertical shaft 51,arranged to rotate in a bearing 52 upon the base-plate 30 of theform-carrier. Upon the under face of the ink-distribution plate 50 isprovided a ratchet 53, which is rotated by a pawl 54, pivotallysupported at 55 upon an arm 56, which in its turn is fastened to arocker-shaft 57, journaled in a vertical flange 58, Figs. 1 and 4,integral with the base-plate 30. A rocking motion is imparted to the arm56 by another arm 59, fast to the opposite end of the shaft 57 to thatat which the arm 56 is fastened and operated by a pin 60, fast to thesprocketgear 61. The arm 56 is held in the position shown in Fig. 4against a pin 62 by a tension spiral spring 63, one end of which is fastto the pawl 54, the other end to a bracket 64,

fast to the base-plate 30. Said spiral spring holds the pawl 54 incontact with the teeth of the ratchet 53 and also holds the arm 56normally against the pin 62. As the sprocketgear 61 is rotated in thedirection indicated by the arrow thereon, Fig. 4, the pin engages theunder side of the offset 65 upon the arm 59, lifting said arm androcking the arm: 56 toward the right, Fig. 4, moving the pawl 54 towardthe right in said figure and rotating I the ratchet 53 and thedistribution-plate 50 through a space of one tooth in the direction ofthe arrow upon said distribution-plate in When the pin 60 has passed bythe Fig 1.

1 projection 65 :upon the arm 59, thespring 63 fast to the arm 28.

the form-carrier arms.

will draw the pawl 54 and arm 56 toward the left, Fig. 4, bringing thearm 56 against the stop-pin 62 and the pawl 54 into engagement with anew tooth in readiness to be actuated by the pin 62 upon its nextrotation.

The ink-carrier rolls 66 66 are each fast to a shaft 7 9,which rotatesin bearings 67, formed in the links 68 68 of the sprocket-chains 69 69.Each of the sprocket-chains 69 is driven by a sprocket-gear 61, fast toa shaft 70, which rotates in bearings 71 in the form-carrier arms 28 29.Each of the sprocket-chains 69 passes from one of the sprocket-gears 61around a sprocket-gear 72, said gears 72 being idlers and journaled torotate upon an adjustable stationary shaft 73. Said'shaft is preferablyrectangular throughout its length except at the two ends thereof, whereit is made cylindrical to receive the sprocket-gears 72 72. The shaft 73passes through slots 74 74 in the right-hand end, Fig. 4, of thevertical flanges 58 58 upon the form-carrier 25 and is adjusted to takeup any slack in the chains 69 bymeans of adj usting-scr'ews 75, havingscrew-threaded engagement with said shaft'and bearing at the left-handend thereof against'a transverse rib 76, integral with the base-plate30, the object of this adjustment being to keep the sprocket-chains 6969 tight, so that the rolls will 11 ot sag as they are being carriedacross the upper face of the ink-distribution plate 50, around the type,across the face thereof, and back to said ink-distribution plate.

The shaft to which the sprocket-gears 61 are fastened is rotated by aspur-gear 77, keyed thereto and meshing into an intermediate gear 78,which rotates upon a stud 79, The intermediate gear 78 is driven by thegear 36.

In order to guide the ink-carrier rolls 66 66' with percision across theface of the type and to prevent the sprocket-chain 69 from sagging andalso in order to hold said ink-earrierrolls again st the surface of thetype with a yielding pressure as it passes thereacross, I provide uponeach side of the form-carriera plate 80. Said plates are provided withcylindrical bosses 81 81, each of said bosses being provided with avertical cylindrical. recess 82, in

which is located a spiral spring 83, the upper end thereof bearingagainst the'upper end of the recess 82, the lower end thereof bearingagainst a head 84 upon a bolt 85, said bolt being screwthreaded at itsupper end to e11- gage a boss 86, formed upon the under side of Each ofthe plates is provided with a groove 87 upon its inner face, whichreceives the friction-rolls 88 88, fast to each end of the shaft 79, andguides the ink-carrier rolls 66 as they pass across the face of thetype, holding said ink-carrier rolls against the face of said type witha yielding spring-pressure, due to the fact that the plates '80 are heldupwardly with a spring-pressure by the spiral springs 83, hereinbeforedescribed. It will be noted that the grooves 87 are beveled downwardlyat each end 89 89 in the plates 80 willbe pushed downwardly, thus,bringing into action the spring-pressure heretofore referred to, and asthe rolls leave the groove this downward inclination releases the plate80 without jar.

Ink is transferred from the ink-supply roll i 44 to the ink-distributionplate by a brayerroll 90, journaled to rotate in bearin gs 91,

fast to flat springs 92, said flat springs being in turn fastened torocker-arms 93 by means of a clamp-plate 94. The rocker-arms 93 arefastened to a rocker-shaft 95, journaled in bearings 96 96, formed inbrackets 97, fast to the brackets 42 43. Arocking motion is given totherocker-shaft 95 by an arm 98, connected by a link 99to a crank-arm100,,fast to the rotary sprocket-shaft '70.

The operation of the mechanism hereinbe- 'fore described is as follows,it being understood that the form-carrier 25 is raised and lowered bythe connecting-rods 38 and that the crank-arm 1.00 is given a constantrotary motion by the shaft through the gears 7 7 78, and 36, the gear36being rotated by the shaft 31, to which it is keyed, said shaft 31 beingrotated by the sprocketgear 35 and chain 37 The different consecutiverelative positions of the form-carrier 25, ink-supply roll 44, crank-arm100, link 99, brayer-roll 90, rocker-arms 93 and 98, inlcdistributionplate 50, and ink-carrier rolls 66 are illustrated in Figs. 6, 7, 8, 9,2, 10, 11, and 12 in the order named. In each of said figures the arrowsa, b, e, (Z, e, and f indicate, respectively, the directions in whichthe form-carrier 25, the crank-arm 100, the rocker-arm 98, thebrayerroll 90, the ink-supply roll 44, and the inkcarrier rolls 66 aremoving or rotating, as the case may be. By reference to said figures itwill be seen that in Fig. 0 the form-carrier is L to descend.

50. the ink-carrier rolls have passed to the left of the type, and thebrayer-roll has passed to in its uppermost position and just startingThe ink-carrier rolls are passing across the face of the type, and thebrayer roll is at the right-hand end of its reciprocatory motion uponthe ink-distribution plate In Fig. 7 the form-carrier is descending,

the extreme left of the ink-distribution plate.

In Fig. 8 the formcarrier is still descending,

the inkcarrier rolls are passing upwardly,

,1 and the brayer-roll has been brought into contact with the ink-supplyroll. In Fig. 9 the form-carrier is still descending, the ink-carrierrolls are coming into contact with the inkdistribution plate, and thebuyer-roll has beenbrought to its uppermost position in contact with theperiphery of the ink-supply roll. In Fig. 2 the fOrm carrier hasdescendcontact therewith. In Fig. 10 tlie'form-carrier is'movingupwardly, the ink-carrier rolls have passed to the right beyond theink-distribution plate, and the brayer-roll has been moved upwardlytoward its uppermost position in contact with the periphery of theinksupply roll. moving upwardly, the ink-supply rolls are approachingthe type from the right-hand side thereof, and the brayer-roll, still incontact with the ink-supply roll, is moving upwardly thereon. In Fig. 12the form-carrier is moving upwardly, the brayer-roll has been moved backinto contact with the ink-distri- In Fig. 11 the form-carrier is butionplate at the left-hand side thereof, and J the ink-carrier rolls are incontact with the type. It will thus be seen that the gearing whichrotates the sprocket-shaft 70 is so proportioned to the gearing whichraises and lowers the form-carrier head that the bra-yer-roll will passfrom the right-hand side of the distri bution-plate, Fig. 6, to the leftof said plate, Fig. 7, thence to the ink-supply roll, Fig. 8, upwardlyin contact with the periphery of said roll, Fig. 9, downwardly upon saidperiphery,

Fig. 2, upwardly, Fig. 10, downwardly, Fig.

11, back to the ink-distribution plate, Fig. 12, and next to theposition shown in Fig. 6 at the left of said plate, so that in one cycleof operation or in one rotation of the main driving-shaft of the machineand during one up-- ward and downward motion of the form-carrier thebrayer-roll is given one oscillatory motion forward and back upon theink-distribution roll and two oscillatory motions up and down in contactwith the periphery of the ink-supply roll.

It is evident that an endless band with bearings attached thereto forthe ink-carrierrolls ICO mightbe substituted in place of thesprocketchains 69 without departing from the spirit of my invention andalso that the brayer-roll instead of being supported upon a flat springuponthe rocker-arm 93 may be journaled in bearings 101, formed inrocker-arms 102, said rocker-arms 102 being fast to a rock-shaft 1.03,journaled in the rocker-arms 104, said rocker-arms 104 being fast to theshaft 95. A torsional spiral spring 106 is fast at one end to one of thearms 104 and atthe opposite end to a collar 107, which is fastened by asetscrew 108 to the rocker-shaft 103, so that the tension upon thespring 106 may be adjusted by turning the collar 107 in the properdirection, fastening it to the rocker-shaft 103 by means of saidset-screw 108.
